An allusion is a figure of speech that makes a reference to, or representation of, a place, event, literary work, myth, or work of art, either directly or by implication. There are many found in the text of To Kill a Mockingbird, and I have provided several examples from Chapters 4-8.

CHAPTER 4. There is an allusion to the Rover Boys, a series of books for young readers of the 1930s; Hot Steams, a type of ghostly apparition; and the L&N Railroad.

CHAPTER 5. The World War I Battle of the Marne is mentioned as is Confederate cavalry commander General Joe Wheeler.

CHAPTER 8. The ancient Rosetta Stone is referenced in relation to Mr. Avery; the Civil War surrender site of Appomattox is mentioned; and another book series, Tom Swift, serves as an allusion.
